我已经尝试从 PPA 安装软件包几个小时了。我正在运行新安装的 ubuntu 14.04 版本。
我一直遵循这些说明： https://github.com/ethereum/go-ethereum/wiki/Installation-Instructions-for-Ubuntu
发出此命令时：
sudo add-apt-repository ppa:ethereum/ethereum
我收到了五个此类错误：（全部添加到帖子底部以供参考。）

softwareproperties.ppa.PPAException: 'Error reading https://launchpad.net/api/1.0/~ethereum: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:600)'
我认为这与以下这句话有关：
[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:600)'
我尝试重新安装并更新 ca 证书。并且我运行了 apt-get update 和 upgrade。（我也尝试了 15.04，但结果相同）
我是否必须为该特定主机添加/生成证书？
有什么想法我可能会遗漏什么吗？
谢谢您的帮助！

答案1
您可以尝试以下几种方法。首先，您是否尝试过手动ethereum-ethereum-<version>.list为以太坊创建一个新文件/etc/apt/sources.list.d/？如果真的是验证错误，我怀疑这样做不会有什么不同，但如果 apt 只是有点问题，那么这样做就可以了。您想要放入该文件中的行类似于：
deb http://ppa.launchpad.net/ethereum/ethereum/ubuntu trusty main
您还可以尝试的另一件事是，如果您信任以太坊，则可以将标志传递allow-unauthenticated给 apt-get，这可能会成功。这是不是一个特别好的主意。
apt-get --allow-unauthenticated add-apt-repository ppa:ethereum/ethereum
你可以也尝试从以太坊下载证书，但粗略浏览他们的博客表明他们不太热衷于签署权力，所以我不知道这种方法是否可行。
